    Cisco VPN

    Hi Joeddali, Assuming that users are connecting to the VPN Concentrator with Windows VPN client, there are options for using CLIENT ip address. You can configure the Concentrator to use Client ip address or Server assigned ip address. Now You said that the clients with static ip can talk...

    can't ping single host

    Hi, What kind of access-lists do u have on the 2600 router and also please see if you can see the MAC address of the laptop in the switch's cache (what kind of switch, for cisco, you could use "show cam"). Cheers, Rajesh

    new on VPN

    Okay lets see... You have a public ip address for your VPN server so that any internet user can connect to it? All you need to do is to configure the server for VPN server and clients. Look at the link and let me know if that helps...

    VPN shuts down networking

    Can you explain how your connection is? You have 3000 Concentrator on your side and what is that you have the other side and are you using? When you say you cannot access which network is that? Cheers, Rajesh

    Cisco 2620 w/ 515e PIX unit

    I am a little confused here.. Well, lets see. you have a pix box and a 2600 router and you want to do IPSEC between them. If that is the case, the VPN is possible. Now the question is what kind of VPN? Then.. you can have a VPN tunnel between 2600 and PIX. If the situation is as below...

    new on VPN

    If you are using ISA for firewall, all you need to do is to open the protocols and ports for the VPN traffic. Let me know what kind of VPN (VPN Protocols) you are using and then I will find out the required ports for you. For example; if you are using ipsec, all you need to open is port 500...

    new on VPN

    Use this link as a start and then you can dig more details from Microsoft site. You can setup RRAS on your ADv.Server and configure client connections on other PCs. You can use PPTP, L2TP, or IPSEC. http://www.eits.uga.edu/nt2000/vpn.htm Cheers, Rajesh

    VPN - INTERNET ACCESS

    Are those IP addresses Public and provided by the Adsl provider? Then it should work! Can you explain some more on what you are looking. Cheers, Rajesh

    CPU inconsistancy

    I thought so! Most of the customers I have worked with have the high cpu utilization because of high traffic or because of high NAT translations. Cisco suggests like 3000 entries but in real customer situatons, they have like 10000-20000 NAT entries which have a high tcp clear out timer set...

    Broadcasts with NAT

    No Chuck, it won't work! I understand what you are tried to tell me, but when a packet reaches a router which is configured for doing natting, the router treats the source address and broadcast address differently. The router simple hates the broadcast address. The only thing it can do is to...

    Broadcasts with NAT

    We are looking at two issues here. As I said before; you can use the NAT on a router to have the machines behave as if they are on both networks. But broadcast is a totally different idea. You can't correlate them because when you do NAT, you are natting the source address. But broadcast...

    IP adress and differents passwords ?

    Hi, You can setup your pix firwall as a VPN server and have the users use Cisco's VPN client to login. An example would be the users dial in to their ISP and from there they use the vpn client to connect to the PIX. Here you can have the PIX provide dynamic ip address for your clients for...

    VPN - INTERNET ACCESS

    Let me understand the question first. You have 2 sites having dsl connections to the service provider and you want to create a vpn tunnel between these two sites and also use internet. Yes it is possible. By the way.. No question is a Dumb Question :) Cheers, Rajesh

    Broadcasts with NAT

    First of all, the router won't pass the broadcast. Now if you want it to pass the broadcast to one specific host on the other side, you can use "helper address". For example, say I have a dhcp server 10.10.10.10 and I have dhcp clients on 172.0.0.1 interface of the router. Then you can...

    CPU inconsistancy

    You were previously using "ip route-cache same interface"? Do you have secondary addresses configured on the same interface? By just adding ip route-cache, you have enabled fast switching which reduces the cpu overhead caused by the process IP INPUT. can you put a sample "show...

    cisco 1751 with a cable modem

    I have a 2513 router and I connect the ethernet port on it to the cable modem directly and have enabled to pick up Ip address from DHCP. The other interface goes into a switch where I have multiple machines connected. Dunno whether you are looking for this! Cheers, Rajesh

    cant ping my gateway...

    If you have tried all the normal routines and you are having intermittent problems (ping), then I would suspect it is a tcp/ip stack problem. In WIN XP, it happens and try reinstalling tcp/ip itself. Cheers, Rajesh

    correct path for winsocks

    I'm not sure I understand your question. Are you asking where in windows foler these files are? Then it is in c:\winntsystem32 Cheers, Rajesh

    Can you describe what is that you are doing and what you want to achieve? Cheers, Rajesh

    Cisco 2600 NAT problem

    Hi James, I am not sure I understood your question correctly! It seems to me that you have 2 private networks connected through a router and you want them to talk to each other. All you need to do is to connect these networks to the router and thats it. The router will do the routing and you...
